Eukaryotic mRNA Sequencing-Illumina
Features
● Capture of poly mRNA prior to library preparation
● Optional directional mRNA library preparation to enable obtaining strand-specific sequencing data
● Bioinformatic analysis of gene expression and transcript structure
Advantages
● Extensive Expertise: Our team has processed over 200,000 samples at BMK, spanning diverse sample types such as cell cultures, tissues, and body fluids. We bring a wealth of experience to every project and have successfully completed over 10,000 mRNA-Seq projects in various research domains.
● Rigorous Quality Control: We implement core control points across all stages, from sample and library preparation to sequencing and bioinformatics. This meticulous monitoring ensures the delivery of consistently high-quality results, assuring you that your project is in reliable hands.
● Comprehensive Annotation: We use multiple databases to functionally annotate the Differentially Expressed Genes (DEGs) and perform corresponding enrichment analyses. This comprehensive approach provides insights into the cellular and molecular processes underlying the transcriptome response, ensuring you are fully informed about your project's results.
● Post-Sales Support: Our commitment extends beyond project completion with a 3-month after-sale service period. During this time, we offer project follow-up, troubleshooting assistance, and Q&A sessions to address any queries related to the results.
